Abstract
To address the payload compartment layout problem for high-density instruments and e-quipment on large spacecraft,a two-stage layout optimization algorithm is proposed in this pa-per.A segmented strategy is adopted to focus on the dominant technical constrains,and the high-dimensional,multi-constraint optimization problem is reformulated as two serially coupled layout optimization stages for solution.First,the allocation of heat pipes to equipment components is formulated as an integer programming problem.The final heat-pipe allocation is then determined by successively introducing constraints on the maximum thermal power consumption of heat pipes multi-energy capacity,longitudinal layout dimensions,special component layout require-ments,and component centroid constraints.In the second stage,a detailed layout optimization model is established based on the obtained allocation relationships.The movement range of com-ponents is reduced,the centroid distribution is optimized,and the final the design results are ob-tained,yielding a layout design scheme with determined equipment positions.Through a payload compartment layout design case involving 119 pieces of equipment,a satisfactory layout scheme is obtained,demonstrating the capability of the proposed method to handle large scale and complex de-sign problems.In particular,when centroid constraints are not overly stringent,the method can effec-tively generate feasible layout solutions,indicating promising potential for engineering applications.关键词
